 This is a very simple way, an effective way to improve athletic performance. And this one is almost never considered among athletes and that's to improve mobility. So mobility is defined as your joints ability to express itself fully through its fullest range of motion with control and strength. Mobility does not mean you're flexible. Flexibility is a component mobility. Mobility means you are not only flexible, but you own the entire range of motion. So not only can you do the splits, but if you need to jump out of the splits, you could, or if somebody jumped on top of you while you're in the splits, you wouldn't hurt yourself. For example, mobility is what will allow you to perform better on the field or on the court, because now whatever strength you have, you have now extended its range of motion. So however far you reach or rotate or throw or punch, you've now increased the capacity to do so by improving mobility.
